7-26 Communicating with Devices on a ControlNet Link
Example 3: Total Connections Required by DriveLogix1
The following table calculates the connections used in this example.
If you configured the local I/O modules as rack-optimized, you would only
need the DIN-rail connection to the I/O modules, reducing the above
example by 3 connections.
You can configure the 1756-CNB module to use no connection. This is
useful if you configure all direct connections to their associated I/O
modules and do not need a rack-optimized connection.
Connection: Amount:
DriveLogix1 controller to 3 local I/O modules
